| Critètes d'exclusion |
- Relapse occurred within 180 days post allograft
- Refractory to Len at any given time before allogeneic transplantation
- Presence of ≥ grade II or uncontrolled acute GVHD
- Presence of severe or uncontrolled chronic GVHD
- Karnofsky score < 70%
- Bilirubin > 50 μmol/L unless felt to be related to Gilbert's disease or hemolysis; AST and ALT > 5 x upper limit of normal (ULN); alkaline phosphatase > 5 x ULN

Female study participants who are surgically sterile (hysterectomy) or who have been postmenopausal for at least 12 consecutive months are automatically eligible for this criterion

Males not agreeing to use a condom during any sexual contact with females of child-bearing potential from at least 4 weeks before, to at least 4 weeks following discontinuation of Len
- Women who are lactating
- Female of child-bearing potential who are planning to become pregnant while enrolled in this study up to 4 weeks after the last Len dose
- Participation in a trial with an investigational agent within 30 days prior to entry in the study
- Inability to provide written informed consent prior to initiation of any study-related procedures, or inability, in the opinion of investigators, to comply with all requirements of the study
- Estimated probability to survive less than 6 months after initiation of Len and Dex
- Current history of drug and/or alcohol abuse
- Any abnormal condition or laboratory result that is considered by investigators capable of altering patient's condition, compliance or study outcome
- Any patient who, in the opinion of investigators, should not participate in this study
- Having received allogeneic stem cell transplantation in relapse after autologous transplant.
- Having received Len therapy after allogeneic transplant, before relapse
- Poor organ function defined as either: diffusing capacity of the lung for carbon monoxide corrected for hemoglobin using Dinakara method (DLCOc) < 50%; forced expiratory volume in 1 second < 50%; left ventricular ejection fraction (LVEF) < 40% evaluated by echocardiogram or multi-gated acquisition scan (MUGA); uncontrolled arrhythmia; symptomatic cardiac disease; creatinine clearance < 30 mL/minute; liver cirrhosis
